- Pre-reconstitution (lyophilised powder)
- Sealed vial, desiccated
- −20°C in low-humidity freezer
- 24–36 months
- >95% at 24 months
- Optimal long-term storage. This is how research-grade peptides should be maintained before use
- Post-reconstitution (aqueous solution)
- Mixed with bacteriostatic water
- 2–8°C refrigerated
- 28 days maximum
- 90–95% at 28 days, then rapid decline
- Standard working storage. Use within this window or accept significant potency loss
- Frozen reconstituted solution (single freeze-thaw)
- Aliquoted in cryovials
- −20°C, thawed once in refrigerator
- 3–6 months frozen, 24 hours post-thaw
- 80–85% after one freeze-thaw cycle
- Emergency extension only. Acceptable if you can't reconstitute fresh, but expect 10–15% activity loss
- Room temperature (reconstituted)
- Any aqueous solution left out
- 20–25°C
- 6–12 hours before measurable degradation
- 70–80% at 24 hours, <50% at 72 hours
- Hard failure. Never leave reconstituted peptides at room temperature beyond active use
- Refrigerator door storage (reconstituted)
- Standard vial placement
- 4–12°C (fluctuates with door openings)
- 14–21 days realistic
- 75–85% due to temperature cycling
- Suboptimal. Temperature instability accelerates deamidation compared to stable back-of-fridge placement
